Tag: 12 Volt Lead Acid Battery charger

This 6/12 Volt lead acid battery charger circuit provides an initial voltage of 2.5 V per cell at 25°C to quickly charge a Lead Acid battery. The charging current reduces as the battery charges, and when the current drops to 180 mA, the charging circuit reduces the output voltage to 2.35 V per cell, leaving the battery in a fully charged state. This lower voltage helps prevent the battery from overcharging, which would shorten its life. (more…)
